Schedule

Please check the schedule before registering as there are sometimes two workshopes at the same time.

The tentative schedule can be found on this webpage on the left side unter 'timetable'; detailed description of the schedule will be inserted in programme. This is a living document and will be updated regularly. 

Presentations & Contributions

Each participant is required to bring a Poster (max. A0 portrait format) or printed out figures and present them during the Ice Breaker Poster Session. You will present your poster in a lightening poster presentation (1 min) on Tuesday. 

 

No conference fees apply.

 

We are currently still working out the details for the excursion (exploring Potsdam a little) and dinner and will update you as soon as possible on this webpage. Costs will apply.

This will be a brainstorming workshop where we can share our ideas about potential future collaborative projects on this and other topics. 
Please bring slides on: (maximum 3 slides)

1.Examples of species interactions inferred from sedaDNA
2.Examples of network analysis using environmental/ancient genomic data
3.Funding opportunities for collaborative projects
4.Further joint project ideas in other sedaDNA topics

During the workshop we will work on this document, you can already check and add ideas now. If you want to share slides, you can add them there or bring on your stick.

Speaker: Ulrike Herzschuh

13:00 → 15:00 Hands-on Workshop metabarcoding

Implementation of a DNA metabarcoding pipeline using obitools4

OBITools have been around for over 15 years. OBITools4 is their latest version, with a considerable improvement in terms of computational efficiency and ease of installation. During this tutorial, based on the analysis of a toy dataset, we will review the principles behind OBITools, the main algorithms they implement, their advantages and disadvantages.

This workshop is recommended for students and early PhDs.

Speaker: Eric Coissac

15:00 → 15:30 Coffee Break

15:30 → 18:00 Hands-on workshop metagenomics

The hands-on workshop will be about the data analyses pipelines of metagenomic shotgun data.

This workshop is recommended for students and early PhDs.

Speaker: Kathleen Stoof-Leichsenring

15:30 → 18:00 Modelling workshop on detecting aquatic transitions in sedDNA records (PAGES PaleoECOGEN))

The PaleoECOGEN workshop will be split into parts:
- The first part (Thursday) will be an R workshop, open an to all people, on methods used to detect critical transitions. In particular, the workshop will present Online Dynamic Linear Models (Online DML) for uni- and multivariate datasets.
- The second part (Friday), again open to all, will be a bring your own data session followed by a group discussion to brainstorm on potential future collaborative projects. Participants will thus be able to apply the R code from part one of the workshop to their own data (2 hours), and then regroup to discuss commonalities about questions and datasets (1 hr), ending off with a brief discussion of research questions that could be applied to our combined datasets in the future (1 hr).
